Hop plant named ‘BRU-1’

ABSTRACT

‘BRU-1’ is a new hop plant notable for its abundant, dense cones and distinct aroma.

Latin name: Humulus lupulus.

Variety denomination: ‘BRU-1’.

BACKGROUND OF THE VARIETY

‘BRU-1’ is a new and distinct variety of hop plant discovered by theinventor as a chance seedling in a cultivated ‘Cascade’ (not patented)hop field near Toppenish, Wash. ‘BRU-1’ variety has been asexuallyreproduced by cuttings near Toppenish, Wash. and has been observed toremain true to type over successive asexually propagated generations.

BRIEF DESCRIPTION OF THE VARIETY

‘BRU-1’ hop plant was first selected for its abundant, dense cones anddistinct aroma. The cones of ‘BRU-1’ are similar in structure to‘Columbus’ (U.S. Plant Pat. No. 10,956) and ‘HBC 394’ (U.S. Plant Pat.No. 21,289), but can be distinguished from ‘Columbus’ by their fruitieraroma, and from ‘HBC 394’ by their much higher alpha acid content. Acomparison of ‘BRU-1’ to ‘Columbus’, ‘HBC 394’ and ‘Cascade’ appears inTable 1 below.

DETAILED BOTANICAL DESCRIPTION OF THE VARIETY

The following-detailed botanical description is based on observationsmade during the 2016 growing season at Toppenish, Wash. of one-year-oldplants. All colors are described according to The Royal HorticulturalSociety Colour Chart (5^(th) ed. 2007). It should be understood that thecharacteristics described will vary somewhat depending upon culturalpractices and climatic conditions, and will vary with location andseason. Quantified measurements are expressed as an average ofmeasurements taken from a number of individual plants of the newvariety. The measurements of any individual plant or any group of plantsof the new variety may vary from the stated average.
